It is worth mentioning that the conveying speed of the marking assembly 3 in the x direction is determined by the driving assembly 4,the speed of conveyance of the glass sheet 200 in the y-direction is determined by the rotational speed of the rollers on the glass sheet production line 100. For example, assuming that a defect exists at a position on a glass sheet 200, which is detected by the defect detecting assembly 1, and the x-direction and the y-direction marked in fig. 1 are taken as coordinate systems, and one of the corners of the glass sheet 200 is taken as an origin, the coordinates of the position can be assumed to be (x)1，y1)。
As the glass sheet production line 100 is conveyed, the coordinate point x is known1The position relative to the support 5 is constant, while the coordinate point y1The position relative to the carriage 5 is constantly changing, which is the speed of conveyance of the glass sheet production line 100.

It is expected that the tachometer wheel 21 in direct contact with the glass plate 200 may be selected to be a soft material so as not to affect the surface accuracy of the glass plate 200. Further, because the thickness of glass board 200 is diverse, in order to satisfy the commonality requirement for tacho wheel 21 can still be with glass board 200 butt, speed measuring component 2 has still set up transmission shaft 24. Specifically, a plurality of speed measuring wheels 21 are arranged on the transmission shaft 24 in a penetrating manner, the speed measuring wheels 21 can be in transmission connection with the transmission shaft 24 through bearings, two ends of the transmission shaft 24 are respectively connected with one upright column 52, and the transmission shaft 24 is detachably connected with the upright column 52.

Specifically, referring to FIG. 2, the position sensor 6 is connected to the flag assembly 3 and is in signal communication with the controller. If the position sensor 6 does not detect the presence of the glass sheet 200 underneath, the position sensor 6 transmits a signal to the controller, which can control the marking assembly 3 to stop working, i.e. the position sensor 6 acts as a switch for the emergency shut-off function.
For example, if the defect detecting assembly 1 has transmitted the detected data signal to the controller, the controller controls the driving assembly 4 to move to drive the marking assembly 3 to move relatively, at this time, the marking assembly 3 moves to a certain position on the beam 51, waits for the glass sheet 200 to be transmitted, and after the interval time t, the marking assembly 3 can correspond to the defect position coordinate (x) on the transmitted glass sheet 200 exactly1，y1) Carrying out ink jetting operation on the defects; if the plurality of sets of driving rollers on the glass sheet production line 100 are damaged at the moment and the glass sheet 200 is not conveyed, the marking assembly 3 automatically sprays the ink after the same interval time t, which is likely to cause a certain risk.
Therefore, through setting up position sensor 6, even the multiunit driving roller on glass sheet production line 100 takes place to damage, glass sheet 200 is not conveyed over, and after same interval time t, position sensor 6 does not detect there is glass sheet 200 below, and position sensor 6 transmits the signal for the controller, and the controller can control mark subassembly 3 stop work, avoids the unexpected condition to take place.
To sum up the structure, can be right the utility model provides a glass defect marking device's theory of operation describes to be:
the sets of drive rollers on the glass sheet production line 100 rotate to move the glass sheet 200 in the positive y-direction of fig. 1 to effect the transfer of the glass sheet 200. The glass sheet 200 passes through the defect detecting unit 1, and the defect detecting unit 1 detects a defect in the glass sheet 200, and detects the position (x) of the detected defect1，y1)，(x2，y2)…(xn，yn) Converted into a signal to be transmitted to the controller, and the controller calculates a transmission time t required for the defect position on the glass sheet 200 to be transmitted to a position below the marking assembly 31，t2…tn。
The controller receives the signal transmitted by the defect detecting component 1, controls the driving component 4, and drives the marking component 3 to move to x along the sliding rail 4211At position, wait for the glass sheet 200 to pass through the defect inspection assembly 1 t1Time, control the marking assembly 3 to act, at the defect position (x)1，y1) Marking the position; then the driving component 4 drives the marking component 3 to move to x along the sliding rail 4212At position, wait for the glass sheet 200 to pass through the defect inspection assembly 1 t2Time, control the marking assembly 3 to act, at the defect position (x)2，y2) The mark … is marked and so on until all the defect positions (x) on the whole glass plate 200 are marked1，y1)，(x2，y2)…(xn，yn) And finishing all marks. The marking work of the next glass sheet 200 is performed.
The above defect position (x)1，y1)，(x2，y2)…(xn，yn) The same defect can be marked with the same color, or different defects can be marked with different colors.
The utility model discloses an foretell glass defect marking equipment carries out the defect mark to glass board 200, and the controller of glass defect marking equipment can convey every glass board 200's defect information and give subsequent process of cutting.
Since the controller can transmit the defect information of each glass sheet 200 to the subsequent cutting process, it is only necessary for the upstream enterprise to transmit the defect information of each glass sheet 200, i.e., the defect position (x)1，y1)，(x2，y2)…(xn，yn) And transmitting the defect information to a downstream enterprise, and cutting the defect information according to the defect information transmitted by the upstream enterprise by the downstream enterprise according to the requirement.
Compared with the prior art, the cutting device does not need to be cut for the first time in an upstream enterprise and then transmitted to a downstream enterprise for secondary cutting, so that the defect detection and cutting times are reduced, the cost is saved, the rejection rate is reduced, and the waste is avoided.
Referring to the upstream enterprise a, the downstream enterprise b, and the downstream enterprise c illustrated in the background art, the upstream enterprise a does not need to perform a trimming process, but only needs to perform defect detection once, and transmits the defect information of each glass sheet 200 to the downstream enterprise b and the downstream enterprise c. Because the downstream enterprise B pays more attention to the bubble defect and has low requirements on the thickness and the flatness defect of the glass plate, the downstream enterprise B only needs to cut off the part with the bubble defect position, and even if certain thickness and flatness defects exist, the downstream enterprise B can also accept the bubble defect position. Therefore, the upstream enterprise A can sell part of the glass plate 200 with the thickness defect and the flatness defect to the downstream enterprise B at a lower price, and in the prior art, the part of the glass plate 200 can be directly thrown away as waste, so that the income of the upstream enterprise A is improved, and the cost of the downstream enterprise B is reduced.
Similarly, the downstream enterprise A has very high requirements on all defects, and by adopting the production method in the prior art, even if the upstream enterprise A is subjected to the first optimized cutting to form the glass original sheet sold to the downstream enterprise A, the part of the glass original sheet cannot meet the requirements of the downstream enterprise A, so that the detection marking and cutting of the upstream enterprise A are useless in a certain sense, and the production and labor cost of the upstream enterprise A is increased.
The utility model discloses in, because first the upper reaches enterprise need not cut technology, only need third the reference of low reaches enterprise defect information that first the conveying of upper reaches enterprise comes, need not carry out the secondary and detect the mark, directly cut once, just can form the glass board 200 that satisfies third the requirement of low reaches enterprise, reduced adopt confession and process cost, avoided the waste of manpower.
Further, the defect information of the waste products cut by the downstream enterprise C can be mutually transmitted, so that theoretically, the upstream enterprise B and the downstream enterprise B can select products which can be used by themselves from the waste products cut by the downstream enterprise C according to the same defect information, and the downstream enterprise C can sell partial cut waste products to the downstream enterprise B so as to increase income.
The basis of the buying and selling mode is that the information of the defect detection of the upstream enterprise A can be mutually transmitted, and the downstream enterprise B and the downstream enterprise C only need to read the defect information to carry out respective cutting. Therefore, the revenue can be increased and the cost can be reduced no matter the upstream enterprise or the downstream enterprise.
